1) i like this to look the way i want, and work the way i want (you can also edit the menu and dialogs) things that work well deserves to look well. I like things that I use often to match the personal/customized look I have going at the moment. All this is prefectly safe as it doesn't directly mess around with program code itself, well not if the author start "hard-coding" it.
2) why not have smaller files if the app loading time doesn't decrease by it (sometimes actually speeds it up) and it can help block against things like virus from infecting the compressed file
